SBL-CORR-2026-001: The historical input-probe disclosure overstates coverage. Unload-only transmissions were not reliably recorded. Focus and blur handlers could run, and per-field failures were not fully counted. These reports cannot establish absence of input transmission outside their retained observations.
Incomplete evidence: evidence was cut short before completion (request evidence was censored before completion — the producer recorded an additional collection loss (recorded loss count: 2)). Counts for the affected evidence are lower bounds; families that completed carry only their ordinary limits. The evidence receipt states the exact per-visit quality.
What this actually means
chase.com triggered fingerprint-like browser API patterns.

The scan observed signals a non-expert should not have to decode from raw request tables.
The cards below translate the evidence into plain language. Where a measured distribution exists, severity ranks this visit against percentiles from the report's exact schema, methodology, tracker-catalog, ServiceRole-taxonomy, metric-contract, producer, and Global Privacy Control cohort, with each percentile card naming its metric-specific measured-site denominator (among 99 sites with a successful load across all cohorts; other methodologies, request-capped visits, and post-choice consent visits are excluded from this denominator, while failed or block-page attempts are outside that coverage), a curated set of popular, mostly commercial sites, not a random sample of the web, and otherwise uses fixed reference thresholds. The request log, domain table, and methodology remain below for verification.
54 requests observed in one controlled visit.
Context
2 of 53 requests the engine evaluated matched Brave Shields filter lists
2 requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser, while loading normally.
Computed with Brave's own ad-block engine and default filter lists in classification mode: matched requests were not blocked by the scanner and remain in this report's observed request counts. Matching shows what Shields would target on this visit's traffic; an actual Shields visit blocks these and also prevents their follow-on requests, so this number is neither a measured block count nor the total effect.
The hand-curated service catalog separately matched 0 request rows in this visit.Show matched requests
Context
This GPC comparison supports no comparable delta
The pair did not record the network egress region for both visits, and an unrecorded condition never counts as matching. and The variant visit did not completely capture this evidence family, so its values are unavailable or incomplete rather than comparable totals.
The raw request logs of both visits remain below for transparency, but the diff between them supports no claim about what the compared condition changed.
2 disqualifying conditions named by the report's claim policy.
Context
Privacy policy read; it made no statement this scan can check
None of the statements this scan knows how to check appear in the policy text, so nothing was compared against this visit's evidence (no catalogued tracking companies observed to check against it). That is a limit of the automated check, not a finding about the site either way.
Statements checked automatically: blanket no-cookie claims, third-party-cookie claims, and combined do-not-sell-or-share claims against advertising-pixel identifier fields. Global Privacy Control claims are never checked against request counts, which cannot show whether selling or sharing stopped.
Policy at https://www.chase.com/{seg}/{seg}/{seg}/privacy/{seg}; 0 checkable statements matched; no catalogued tracking companies observed to check against it.
Context
No known services matched
This scan did not match any third-party domains to the service catalog or another identity source.
No known operator or catalog entity was matched. This scan could not identify 2 of the 2 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.

Nothing observed
No requests to major-platform domains were recorded
No requests to catalogued Google, Meta, TikTok, X, Microsoft, LinkedIn, or Pinterest domains were observed in this visit.
Major-platform domains were not observed in this single passive visit; interaction-gated requests could still load for real users.
These heuristics look for behavior patterns such as canvas readback after drawing, repeated canvas font measurement, WebGL entropy reads, offline audio rendering, or WebRTC peer-connection setup. They are review prompts for this visit, not proof of cross-site identity tracking.
2 canvases matched; reads: canvas.toDataURL, 1 offline render with audio.OfflineAudioContext.createOscillator and audio.OfflineAudioContext.startRendering, 119 measureText calls across up to 69 fonts; measured text contents are not stored and 9 parameter reads and 1 pixel readback; parameters: webgl.getParameter.UNMASKED_RENDERER_WEBGL and webgl.getParameter.UNMASKED_VENDOR_WEBGL, plus 1 other

cut short: request evidence was censored before completion — the producer recorded an additional collection loss (recorded loss count: 2); recorded by the scanner
Recorded provenance is self-reported measurement metadata, not a cryptographic attestation. The public versioned report JSON contains the retained public evidence; see the methodology for interpretation and retention limits.
This report covers what the scanner measures, not everything a site can do. 17 browser surfaces are not instrumented at all (Every page except the one that was scanned; Anything that only loads after scrolling or interaction; Why a request happened, as a causal chain; and 14 others), 3 capabilities are declined by policy, and 3 are outside what any single visit can see. Their absence from this report is not evidence that they did not occur. Read the published coverage boundary.
Detector accuracy is unmeasured. No calibration study currently publishes a precision or recall for the detectors on this page, so a detector match here is a recorded observation, not a calibrated classification. A study has been recorded for pixel-events and does not support a published rate under the current build. How detector accuracy is measured.
Approved use boundary: This report is investigative evidence that requires independent corroboration. It is not a standalone legal determination and not the sole exhibit in a legal proceeding. Recorded in this project's release manifest on .
